ANTISKIDDING SHOE FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Dec. 15,1908.

Application filed February 25, 1908. Serial No. 417,761.

To all whom it may concern:

Be it known that I, GEORGE W. CON- STABLE, a citizen of the United States, residing atWayne, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Antiskidding Shoes for Automobiles, of which the following is a specification.

This invention relates to anti-skidding shoes for automobile wheels, especially ada ted tobe used on heavy vehicles, such as elivery wagons, the object being to provide a shoe which can be easily and uickly placed on the wheel, and one which w en in position will besecurely held thereon, and

prevent the wheel from skidding or slipping.

Another object of my invention is to provide the shoe with very novel means for se curing it in position on the wheel, whereby it will be held tightly thereon, so as to revent the same from rattling or working o'ose in any way so as to injure the tire.

Another object of my invention is to provide the shoe with detachable calks, whereby new ones can be readily inserted when they become worn. I

Another object of my invention is to provide a shoe which is exceedingly simple and cheap in construction, and one which is very strong and durable.

These objects are obtained b the novel arrangement and construction 0 parts hereinafter fully described and shown in the accompanying drawin s, in which: I

Flgure 1, is a si e elevation of a Wheel showing the application of my improved shoe. Fig. 2, 1s a perspective view of-the shoe detached. Fig. 3, 1s a section taken on line 33 of Fig. 1. Fig. 4, is a detail section through the connecting bar and. head of clamping screw. -Fi 5, is an inverted plan view of the shoe, and, Fi 6, is a detail section of the shoe showing t e manner of securin the calks in the shoe.

In the drawings A, indicates a vehicle wheel on which are arran ed my improved shoes B, and in practice have found that three are sufficient to prevent the same from slipping or sliding, but, it of course being understood, that as many can be used as desired.

The shoe com rises a 10 channel plate provide disposed ears C, adjacent its ends, in who are pivotally mounted links D and E, the links being covered with packing material F,

itu dinally curved with oppositel so as to prevent the same from injuring the felly of the wheel when arranged thereon. The links D, are provided wlth connect' bars G, having a hooked end G, adapted to fit under the respective link E, and connect the links together, and in placing the shoe on the wheel, the shoe is placed directly over the spoke, so that the connect' bars G, will pass over the felly between t e spokes and old the shoe in position.

Central threaded bosses G are formed in theconnecting bars G, in which are mountedclamping screws H, having heads I, swiveled on their lower ends, over which are secured leather washers J, adapted to bear against the felly of the wheel.

The outer ends of the clamping screws are provided with eyes, in which an instrument can be inserted, so as to force the clamping screw down tightly against the felly, which will draw the shoe tightly against the wheel so that it will be impossible for the same to move.

It will be seen that as the clamping screw is forced down upon the felly, the connecting bars will be forced up against the ends of the links and securely held in that position, so that it will be impossible for the same to accidentally become detached.

, Threaded bores are formed in a zig 'zag manner in the shoe, in which the threaded shanks K, of calks K, are ada ted to be secured, so as to prevent the shoe om skidding or slipping, and it will be seen that when these calks become worn, they can be readily replaced by new ones, by simply unscrewing the same with a wrench and screwing in new ones.

From the foregoing description it will be seen that I have provided a shoe which is composed of a'very few parts, which are so arranged that they are not likely to get out of order, and one which whenattached will not injure the tire or wheel in any way.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1 An anti-skidding shoe for vehicle wheels comprising a lon 'tudinally curved channeled plate in the orm of a segment of a circle having a studded outer surface, links carried at each end on opposite sides of said plate, each link having mner and outer transverse bar's, cross bars adapted to engage over the folly ofa wheel pivoted to the inner bars of the links on one slde of said plate and each ioo der the inner end bar on the opposite link,

said'connecting bars having screws extending therethrough, each screw having a plate swiveled to its inner end ada ted to fit against the inside of the whee felly, the other end of each of said screws being formed with means whereby they may be turned.

2. An anti-skidding shoe for vehicle Wheels comprising a longitudinally curved channeled plate in the form of a segment of a circle having a studded outer surface, the material of said plate at the sides thereof being formed into outwardly projecting lugs which are bent over to form hooks, opposed metal links having inner and outer transverse bars, the outer of said bars being received within said hooked ears to have pivotal engagement therewith, the inner bar of each link on one side of the shoe being provided with across bar pivoted thereto and adapted to engage over the folly of a wheel, the free end of said cross bar being hooked to engagie under the inner transverse bar of the lin on the opposed side of the shoe, each cross bar having a threaded boss thereon, a clamping screw passing through said boss carrying on its lower end the swiveled plate adapted to bear against the inside of a felly of a wheel each screw at its upper end having means whereby the screw may be turned.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
